Was Saint Luke a medical doctor?

There is no definitive evidence that Saint Luke, the evangelist and companion of Saint Paul, was a medical doctor. The Gospel of Luke and the Acts of the Apostles, both traditionally attributed to Luke, do not explicitly state that he was a physician. However, there are several passages in these texts that have led some scholars to believe that he may have had medical knowledge or training.

For example, in Luke 4:38-40, Luke describes Jesus healing Peter's mother-in-law from a fever. He uses the Greek term "pyretos," which is a medical term for fever, and accurately describes the symptoms and progression of the illness. In Acts 28:7-8, Luke describes the healing of the father of Publius, the governor of Malta. He uses the Greek term "dysentery," which is a medical term for a diarrheal disease, and accurately describes the symptoms and treatment.

These passages, along with other references to medical conditions and treatments in the Gospel of Luke and the Acts of the Apostles, have led some scholars to conclude that Luke may have had some medical training or experience. However, it is important to note that these passages could also be explained by Luke's close observation of and interaction with medical practitioners during his travels with Saint Paul.

Therefore, while there is no conclusive evidence that Saint Luke was a medical doctor, the passages in his writings that demonstrate medical knowledge or terminology have led some scholars to believe that he may have had some medical background or training.
